  • the invention also relates to the process for preparing them and to their use in pharmaceutical compositions for use in human or veterinary medicine, or in cosmetic compositions.
  • vitamin A and its derivatives Compounds with activity of retinoid type (vitamin A and its derivatives) are widely described in the literature as having activity in cell differentiation and proliferation processes. These properties give this class of compounds great potential in the treatment or prevention of numerous pathologies, and more particularly in dermatology and cancer. Many biological effects of retinoids are mediated by modulating the nuclear retinoic acid receptors (RAR), which are factors for transcribing ligand-dependent genes.
  • RAR nuclear retinoic acid receptors
  • RAR receptors activate transcription by binding to DNA sequence elements, known as the RAR Element (RARE) response elements, in the form of a heterodimer with the retinoid X receptors (known as RXRs).
  • RARE RAR Element
  • RAR ⁇ Three subtypes of human RARs have been identified and described: RAR ⁇ , RAR ⁇ and RAR ⁇ .
  • Patent US 6 218 128 itself describes a family of bicyclic or tricyclic molecules.

  • the activation of receptors with an agonist (activator) in HeLa cells leads to the expression of a reporter gene, luciferase, which, in the presence of a substrate, generates light.
  • the activation of the receptors may thus be measured by quantifying the luminescence produced after incubating the cells in the presence of a reference agonist.
  • the inhibitory products displace the agonist from its site, thus preventing activation of the receptor.
  • the activity is measured by quantifying the reduction in light produced. This measurement makes it possible to determine the inhibitory activity of the compounds according to the invention.
  • KdApp Kd apparent
  • an IC 50 value concentration that inhibits 50% of the activity is calculated by plotting the curve of the product at the concentration of the reference ligand that gives 80% activation.
  • the HeLa cell lines used are stable transfectants containing the plasmids ERE- ⁇ Glob-Luc-SV-Neo (reporter gene) and RAR ( ⁇ , ⁇ , y) ER-DBD-puro. These cells are inoculated into 96-well plates at a rate of 10 000 cells per well in 100 ⁇ l of DMEM medium without phenol red, and supplemented with 10% defatted calf serum. The plates are then incubated at 37°C and 7% CO 2 for 4 hours.
  • test products of the reference ligand (4-[2-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthyl)propenyl]benzoic acid
  • 100% control 100 nM 4-[2-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthyl)propenyl]benzoic acid
  • 0% control 500 nM 4- ⁇ (E)-3-[4-(4-tert-butylphenyl)-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthyl]-3-oxopropenyl ⁇ benzoic acid
  • the plates are then incubated for 18 hours at 37°C and 7% CO 2 .
  • the results obtained with the compounds according to the invention clearly show Kd app values ⁇ 100 nM and an IC 50 value ⁇ 100 nM for at least one of the receptor subtypes, this-clearly demonstrating a reduction in the signal, and in the luminescence in the presence of the reference agonist.
  • the compounds according to the invention are thus clearly inhibitors of retinoic acid receptors (RAR).
  • This example illustrates various concrete formulations based on the compounds according to the invention.
